Biolume Egg // Biolume Serpent
A wall you want to sacrifice. A 0/4 defender that scries 2 when it lands filters two draws while it stalls the ground, but the real design is the sacrifice clause underneath, which hands the egg a second life the moment something eats it. A sacrifice outlet turns this from a defensive speed bump into a two-part payoff, and the return timing (transformed at the next end step) sidesteps the summoning-sickness problem cleanly: the Serpent arrives already flipped and ready to swing. The back half is where the mana-base tax comes due, because sacrificing two Islands to make it unblockable is a genuine cost, the kind of blue-flavored self-mutilation that anchors the card in a dedicated Island-heavy shell rather than any two-color splash. The two faces cohere by splitting labor across the transform line: a passive filtering body that does nothing but block early, and an active, resource-hungry finisher that gets hard to answer once the game state and your graveyard tools line up. The scry keeps it relevant when drawn late; the sacrifice-and-return keeps it relevant when your deck is built to feed it.
